 Blue staining of mycelium or mold?

Hello, Shroomery.
Everything's been going pretty well for me (much less contamination) but I just noticed a lot of blue color at the top of many of my jars. I'm used to small amounts of blue staining on the mycelium, but some of these jars have very solid, consistent blue color near the top of the jar. The very dark color came mostly on fully colonized jars.
I took the lids off of one of the jars to observe the blue region. After reading the advice below, I judged the spot to look slightly more like spilled ink. It wasn't bumpy like grains of sand but it's just so dark that it's got me worried.

Bruising looks like a stain, as if you spilled blue ink on the cake and it soaked in. Mold looks like sand, as if you poured green or blue sand on the surface and it remained on the surface.

Here are some pics:
  
  
It's the same color as the staining on the fruit bodies, but it's just so much thicker that i've ever seen it. What do you guys think?

I want to say bruising, but it's only a guess. I'm not very experienced and I'm unfamiliar with grain, so don't take my word as anything more than that.

Definitely contaminated. Shouldn't have even opened that jar up. 
Toss that shit ASAP.

To elaborate on my earlier post (was about to leave for work at the time) I have gotten VERY dark bluing at the tops of my PF-jars that looks quite a bit like this, and it went away about a day after dunking.
So if it's already opened and contaminated, couldn't hurt to isolate and try to just fruit the jar instead of casing like I assumed you would be doing since you're using grain. That way if it isn't a contam it isn't wasted months of colonization and you at least get something for your efforts, and if it is, it's isolated. You can build mini Fruiting chambers for 1 jar for maybe $15.
Once again see above disclaimer.

That looks like a contaminant mold. The grey/blue is more like another mycelium than a stain on the mushroom mycelium.
Did those jars take a long time to colonize, judging based on how shriveled the grain and shrunken the substrate is? Taking a long time would be another indication of contamination.

No, actually these jars took off nicely and colonized quick. All the jars were inoculated G2G, which could help explain a heavy bluing reaction. I was doubtful it's mold because the jars were healthy and already colonized when I all of a sudden noticed a lot of heavy bluing in the same spot on a number of jars.

I should also mention:
smell of the jar was typical mushroomy.

Try washing the cakes. I believe in another thread I read that if it washes off, it's a contam(being mold spores).

That's mold. The pictures you took with flash washed out the image, making it look like bruising. A dry cake will bruise, but not just on top like that. Besides, you can see the thick layer of spores sitting on the surface. Bruising looks like a bruise on your body. That's a separate layer above, indicating mold.
